Solid state lighting apparatus including separately driven LED strings and methods of operating the same

Abstract:

A solid state lighting apparatus can include a first string of Light Emitting Diodes (LEDs) that is configured to operate in response to a rectified ac voltage having a cycle including a null time interval when the first string is off and a second string of LEDs, that is separate from the first string of LEDs, and can be configured to emit light during at least a portion of the null time interval.

Abstract(Chinese):

固态照明装置可以包括第一串发光二极管（LED），其被配置为响应于具有包括当第一串关闭时的零时间间隔的周期的整流交流电压和第二串LED而工作，其与第一串LED分离，并且可以被配置为在零时间间隔的至少一部分期间发光。
